Chromatic organization of primate cones

Science. 1977 Apr 22;196(4288):454-6. doi: 10.1126/science.403607.


The distribution of baboon retinal cones were mapped histochemically by light-stimulated reduction of nitroblue tetrazolium chloride. Blue cones were distributed regularly in the periphery: red and green cones were distributed randomly everywhere. The ordering of cone densities was green > red > blue.
